Is it normal i can't get my sister to be fair?
My mother died in 2000 and my sister & I are the only immediate family members still alive. Because I was travelling at the time, I agreed she could hold on to family records and a writing desk my mother specifically left to me. She is refusing to let me have the desk and for me to go through family records and either take copies or take the originals and copy them for her: all she has agreed to give me are specific papers I've asked for but I'm not sure what else there is. Her excuse about the desk and some of the papers I want is that they're in a storage container at a someone's place and "right up the back" so too hard for her to access.
She's had all this stuff for 18 years and I think it's unfair of her to not give me full access to all the papers and let me have the desk, but she will not listen to me. She is now travelling semi-permanently herself and has been carting family history papers around with her in a caravan!
I want to write about my father's WW1 experiences and his childhood in time for the 100th anniversary in November of the end of WWI (I'm a writer, she's not).
She's quite weird anyway: when my daughter went to see her to let her know I'd had a heart attack, her only response was that she was getting ready to go away for the weekend!
She keeps harking back to an argument we had 8 years ago when she was very unsupportive after I'd been raped and I'm fairly sure told the cops some rubbish which led to them not charging the rapist.
Suggestions please on how I can convince such an unreasonable person to be fair and reasonable.
